XAS of La L3-edge (a), Ti K-edge (b), and O K-edge (c) under different states of charge during the first discharge-charge cycle under 20 mA g−1 at 25 °C. d Contour maps of in situ XRD during the first discharge-charge cycle under 20 mA g−1 at 25 °C. The change (e, f) percentage variation of the lattice parameter (a-axis, c-axis) and the unit cell volume (V) from in situ XRD. g The change of the width a in a-axis direction and height c in c-axis direction of polyhedrons (LiO4, TiO6-1, TiO6-2, LaO12) after lithiation.
